Research on Road Performance of Desulfurized Rubber Asphalt and Mixture

Abstract:

In order to discuss the road performance of desulfurized rubber asphalt and mixture, Swelling mechanism of desulfurized rubber asphalt was studied first, and then performance testing of KLMY90#, normal rubber asphalt and desulfurized rubber asphalt were taken, after that, penetration, shear strength and cohesive strength of desulfurized rubber asphalt mortar were test, road performance of desulfurized rubber asphalt mixture were test at last. The results of the study show that, there is no Rubber particle core, but lots of chemical reaction in desulfurized rubber asphalt; the performance of desulfurized rubber asphalt is better than normal rubber asphalt without high viscosity, easy isolation and poor high temperature storage stability; shear strength and cohesive strength of desulfurized rubber asphalt mortar is better; and desulfurized rubber asphalt mixture have good road performance.
